I finally got a Lito Cruz' photo, after using his metaphor-photo from his blog.
Here is his latest comment.
LI got involved in math during his computer science training. He was lucky to have great professors, taking trig, calculus 1 and 2.
Dr. Cruz is also involved in computer science. Coming from Calvinism, he is much better at discussing the topic than those who chortle over their talking points memorized at seminary and never tested outside their little circle.
